Opionions please--is this an myth or a real problem?

I have read that having a heavy keychain can put quite a bit of pressure on the ignition switch of a car, resulting in premature failure of the ignition switch. What does everyone think about this? The reason that I ask is that I just bought my first brand new car (an '06 Focus) that I plan to keep for 10+ years. If this phenomenon is real I'll try to take a few of the "optional" keys off of my regular daily use keyring to lighten the load. Thanks for your opinions on this matter.

Probably not so much the switch---but the lock cylinder will suffer.
My 94 T-Bird is starting to give me issues, from too many keys on the fob.

Doc here,

The whole assembly can wear out over time due to excessive weight..the Tumblers, the linkage from tumbler to switch ect...BUT then again given enough time it can wear out from use too..( you wouldn't hot wire every time to save wear , would ya ? )

I'd say, If you don't have your military dog-tags, a C~rat can opener, 5 alarm fobs, a 30~30 cartridge, 15 skeleton keys, plastic coated photos of the wife and kiddies .. the grand children and all past generations, hanging off your ring, you should be good to go under normal circumstances..

Perhaps sprinkle a little graphite on the key once a year, and it should last forever..

I'd be more concerned about if the key is a VATS chip key, the key loosing programming long before the switch assembly goes bad..

Doc

on the last 2 cars my mom had she had a heavy chain with many keys. both had problems, the first was a '95 escort, and after a while it could be started with any key on the ring that would fit, and it lost ACC, the second just lost ACC, now she has a '02 Concorde in which only the key and fabb are on a caribiner clip key chain. my cars have seperate rings also.

On Hondas, if you have a lot of extra stuff on the key chain it can interfere with the signal going to the immobilizer(security system) and cause the car not to start.I don,t know about the fords.

The cheap way they make cars today, I wouldn't doubt it...Plastic wears quicker than steel........................The older cars just wear out from years of use.

I hate VATS!!!

I just stared have problems with my 93 TransAm and the whole VATS thing. If I'm in a hurry it takes me about 30 to 40 tries to get it to start without looking at the "SECURITY" flashing at me.

DV8, Your Vats Ignition Switch is bad, have it replaced with a new one, your local locksmith would be able to tell you what your Vats number is by reading the vats key. Soon it will not start at all, after 4 min the Security Light will go out if you have the Ignition in the off position, but Vats Ignition do go bad, and yours is on its way out, leaving you stranded anywhere. Get it fixed soon.
On the other aspect of too many keys on the keyring, I've seen my share of worned out lock cylinders from too many keys on the ring...swinging everywhich way everytime you hit a bump, turn a corner, etc etc. IF you want to replace the Ignition lock cylinder (come visit your local locksmith to do it right...) Keep more than two keys on the ignition switch. The Ford Focus in earlier years 2005 had a manufacturer Recall on the ignition switch,
and if you brought the car new, it was covered by the warrenty.

Thanks!!!

I know it's time for a new tumbler assy. But another ugly fact is my neighbors 5 year old kid was sitting in it and grabbed my turn signal and ripped it out of the column, Broke the little potmetal piece inside. I figure two strikes is enough I guess it's three since i cant easily operate my wipers either...


Sucks to be me!!

Doc here,

Geeze..

Think..3000 pound yard gnome..

Or a Visit to the neighbor kid from Dr Phil.

Other alternatives are: Drive in a straight line..use a screw driver for VATS (and hope the local PD don't notice..And be sure it's on a dry day..) <kidding of course..>

NOW would be a Very good time to R&R the Whole electrical in the steering column (including harness, they usually go first..) Signals (which are 1/2 of your brake lamps) Switch for signals and The wiper control..you going to have to be in there anyway..and that is a job you only want to do once.. (especially if your as Chronologically Challenged as I..)

Doc

bought another column

Just bought a column today. Cleveland pick a part. Real nice guy...150.00 bucks to my door. That includes a key and a new VATS box. The donor car only had 45,000 on it so he says...I'm not looking forward to the R&R.

Doc here,

Now wait...

ON a NEW Honda the Key chain weight is known as the "Stabili Track Steering", lowers the Center of gravity for "those hard corners" ...

ON the OLD Honda it was known as Vehicle speed Governor...

One of My EX's had a BIG brass key ring ..about 9 inches in diameter..had every key known to mankind ... Could probably unlock Fort Knox..AND drove a Pinto...

Every 20,000 miles or so we had to bring it in for a double hernia operation...
